MOLD FOR BUILDING CONCRETE WALLS.

SPECIFICATION forming part of Letters Patent No. 331,11 dated November24, 1885.

Application filed March 17, 1885.

To all whom it may concern.-

Be it known that I, THOMAS W. CARRIOO, of San Antonio, in the county ofBeXar and State of Texas, have invented certain new and usefulImprovements in Molds for Building Concrete \Valls; and I do herebydeclare the following to be afull, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being hand to theaccompanying drawings, which form part of this specification.

My invention relates to an improvement in molds for building concretewalls; and it consists in, first, the combination of the sides of themolds with clamps, which are applied thereto at suitable distances apartand which hold the sides of the mold in position; second, in thearrangement and the combination of the parts,which will be more fullydescribed hereinafter.

This invention is intended as an improvement upon the two patentsgranted to me and dated, respectively, July 8. 1884, No. 301,671, andJanuary 6, 1885, No. 310.377.

Figure 1 is a perspective of an apparatus embodying my invention. Figs.2, 3, 4, 5, 6, and 7 are detail views of the same.

A represents the side pieces of the mold, which are braced andstrengthened at suitable distances apart by means of the metallic cleatsW, which are appliedto opposite sides of each side A of the mold, andclamped together by suitable screw-bolts, as shown in Fig. 1. The cleatsapplied to the inner sides of the sides A are recessed in the sides soas to be flush therewith, and thus leave no mark upon the wall.

The outer sides of these sides A may be given any ornamental shape,design, or configuration that may be preferred, so as to ornament one orboth of the sides of the wall as rapidly as it is built. WVhen the topof the building is reached, or at any suitable points that may bedesired, side pieces having cornices or other ornamental designs may besubstituted for the plain side pieces with which the main portion of thewall has been built.

In order to keep the side pieces, A, perfectly straight and true, andbrace them in position, side beams or braces, U, are applied SerialNo.159,15 9. (No model.)

to the upper and lower edges of the side pieces, A, and which braces Uenable the sides A to be kept perfectly even and true no matter What thelength of the wall may be.

For the purpose of regulating the distance between the side pieces, A,gage-sticks B and D are applied to their upper and lower edges, as fullyshown here, and described in my former patents. Also applied to theouter sides of the side pieces, A, direct or to the outerside of thepieces U, are the clamps which consist of vertical posts T, which areshaped upon their inner sides to correspond to the shape of the wall orfoundation that is being built. To the lower ends of these posts T areapplied roughened metallic plates for the purpose of enabling the clampsto take a firm hold upon whatever part of the mold with which they maycome in contact. Passed through these clamps T, just above the top edgesof the side pieces, A, are the clamping-rods O,which keep the top edgesof the side pieces, A, the required distance apart, and which.clampingrods also serve as fulcra upon which the clamps move when forcedapart or drawn together at their upper ends by the right and left screwthreaded shaft S,which passes through the me tallic plates R,which aresecured to the upper ends of the clamps, as shown. When this shaft S isturned in one direction by means of the handles which are applied to it,the lower ends of the clamps are forced tightly against the sides of themold so as to hold it rigidly in position. These clamps are especiallyadapted for use in trenches where clamping rods, as shown in my formerpatents, cannot well be used. These clamps will be applied to the sidesof the molds at any suitable distance apart.

Where a corner is to be formed, uprights or posts P, having the plate 0with thickened ends applied to their inner sides,will be used, as shownand described in my former patents. The ends of the side pieces, A, willalso have shoulders formed or cut in them, as is there also shown anddescribed, for the purpose of making a perfect joint. Applied to theouter sides of the pieces, A, at a suitable distance from their ends,are vertical cleats X, which are bolted thereto and behind which one endof the clamp V catches. The other end of IOC the clamp catches behindthe post P, and a set-screw which is passed through one end of the clampholds the corner pieces and the side pieces rigidly together. In orderto keep the 5 out-er ends of the side piece A flush with the post P, aplate, Q, is applied to the outer side of the post and made to projectover beyond the end of the side piece, A, as shown, and then a setscrewis passed through this 10 projecting end of the plate so as to bearagainst the side of the part A.

The apparatus by means of which the mold is raised upward when onecourse of the wall has been built is the same as shown in my I 5 formerpatents, and need not therefore be more fully described here.

Where an opening-as, for instance, a Window or door-is to be left in'thewall, a sheet of thin metal or other suitable material,Y, will be 20inserted across the mold, as shown in Fig. 1.

In many cases it is desirable to make the wall apparently solid in thefirst construction, but to have natural breaks in the walls for puttingin doors or windows at some future 25 time. In such-instances the piecesof sheet metal Y are placed in the mold so as to separate the wall atthese points.

Having thus described my invention, I claim 1. The combination of theside pieces, A, 0f 0 the mold with clamps which are applied thereto andmade to bear against both the upper and lower edges of the outsideportion of the mold, substantially as described.

2. The combination of the side pieces of the 5 mold, the clamps, thescrew-rods G, and the shaft S, having right and left screw-threads,substantially as set forth.

3. The combination of the side pieces of the mold with the clamps havingroughened metallic plates applied to their lower ends, the screw-rod O,and the shaft S, having right and left screw-threads, substantially asspecified.

In testimony whereof I affix my signature in presence of two witnessess.
